Title: Small-sized zoom lens
Inventor: SATO HARUO
IPC: G02B15/14
Filed: 1988-12-05
Abstract: PURPOSE:To reduce the weight of the zoom lens and to make the lens compact by providing a 1st lens group consisting of a negative and a positive lens which are arranged separately in order from the object side and 2nd-4th lens groups including at least two positive and negative lenses and satisfying a special condition. CONSTITUTION:The 1st lens group G1 consists of the negative and positive lenses which are arranged separately in order from the object side. The 2nd-4th lens groups G2-G4 each have at least two negative and positive lenses and the respective lens group is moved to the object side while the group interval be tween the 1st lens group G1 and 2nd lens group G2 is increased and the group interval between the 3rd lens group G3 and 4th lens group G4 is decreased to vary the power from the wide-angle end to the telephoto end. Further, this constitution satisfies conditional expressions (1) and (2). Consequently, an about 3 times variable power ratio is secured and the lens is reduced in weight and cost and made compact.

Inventor: INOUE TETSUYA
IPC: A62D101/22
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To ensure a safe decomposing treatment of an object by stroing an object such as dioxine or PCB in a treating container, applying a specified electric energy to between a pair of electrodes facing to each other, thereby generating electric discharge for decomposing the object. SOLUTION: After a specified amount of electrolytic solution 4 is fed to a treating vessel 5 from a supply pipe 8, an electrode supply device is driven to supply an electrode 14 to a position where a tip 14a of the electrode 14 is separated from a liquid level 15 by a specified distance. Then, when a pair of an electrode 3 and the electrode 14 is impressed with a voltage to generate electric discharge, and under the condition a treated object 1 is supplied into the treating vessel 5 from a supply pipe 7, plasma at a temperature of several ten thousands  deg.C generates between the tip 14a and the liquid level 15 due to the electrolytic discharge. At that time, the object 1 and the solution 4 are decomposed by the temperature and the generated energy. The precipitate remaining in a decomposing water 11 is taken out via a discharge pipe 12.

Title: Recording and reproducing device
Inventor: HAYASHI SHIGENORI
IPC: G11B5/72
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to improve the adhesiveness to a magnetic material by providing a magnetic recording medium with a substrate, a magnetic layer and a protective film consisting of diamond-like carbon and forming the thickness of this protective film to a specific value. SOLUTION: The thickness of the protective film is formed to <=50 μm. A PET film 11 of 7 μm in thickness is used as a supporting substrate and the center line average height of the substrate surface is specified to 3 nm. The deposition of the magnetic film 12 is previously executed before the formation of a DLC film. An alloy of CoNi is used for the magnetic film 12. The deposition is executed by vacuum vapor deposition and the film thickness is specified to 200 nm. The DLC film is deposited on the magnetic film by changing the thickness between 10 and 50 nm. When the DLC film is deposited, its coefficient of friction falls to a low level and there is substantially no change in the coefficient of friction in spite of repetition of sliding.  Then, the ruggedness of the surface may be decreased and the magnetic characteristics may be improved while maintaining the coefficient of friction at a low level. The similar strength of adhesion is obtained even by using Ge which is other group IV elements exclusive of Si for the purpose of improving the adhesiveness.

Filed: 1989-11-27
Abstract: PURPOSE:To prevent the collision of an optical system and a lens by moving the lens after the optical system resets to its home position when the magnification larger than an already set copying magnification is freshly inputted. CONSTITUTION:The image light from an original to be scanned by a moving exposing lamp 3 is reflected by 1st to 3rd mirrors 5 to 7 and is imaged via a lens 18 and a 4th mirror 19 onto a photosensitive body 22. The copying magnification is set by respectively moving the lens 18 and the 4th mirror 19. The optical system is always reset to its home position first and thereafter, the lens 18 is moved when the magnification larger than the already set copying magnification is inputted in such a case in which the optical system stops on generation of a jam during a copying operation and the magnification is further changed to a larger magnification after the end of the jam treatment. The danger that the lens 18 comes into collision against the optical system is eliminated in this way.

Title: Driving method for liquid crystal display panel
Inventor: YASUI MASARU
IPC: G09G3/36
Filed: 1987-12-04
Abstract: PURPOSE:To adjust contrast to the contrast meeting a user's desire and to prevent overlap of images by the shadows of black display picture elements by varying the amplitudes of source impression voltages and the pedestal level. CONSTITUTION:A reference voltage Vr and voltages V1-V4 are generated from a voltage source 21 and the relations expressed by the equation are given between the voltages. The magnitudes of V1 and V4, V2 and V3 with respect to Vr are varied by a variable resistor RV to adjust the level. A decoder 17j (j=1, 2,...) selects switching elements Sj1-Sj4 in the combination modes of '1' and '0' of a command signal M for conversion of current to AC and a picture element array signal DSj. The V2 or V3 is impressed to the corresponding picture element electrodes and the picture elements show the gray color between black and white in the case of the picture element array signal DSj=0. The density of the gray color varies with the magnitude of the V2 or V3. Namely, the background is displayed gray and the density thereof is regulated by the variable resistor RV. The double images are then invisible even if the liquid crystal panel is obliquely viewed. The shadows of the picture elements are substantially inconspicuous and the image quality is improved if the density of the background is adjusted.
